WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 234,393, dated November 16, 1880.

Application nien Anni-1,1880. (No model.) i

u into two chambers, each of which is provided with radial paddles. The paddles instead of being vertical are placed at an angle with the vertical sides of the dasher, to which reciprocating'rotarylmotion is applied by means of the mechanism below described.

The object is to produce a washing-machine in which the clothes will not knot or tie up, and in which they are thoroughly washed, the same being the result of the extra and peculiar motion imparted to them while they are in the dasher.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figurell is a side elevation of my machine, a portion of the tub and the dasher being represented as broken out. Fig. 2 is a plan and horizontal section on line x at, Fig. 1. Fig. 3 is a part-vertical section of the tub and dasher. Fig. 4 is a horizontal section on line y y, Fig. 3.

a is a stationary tub resting on the frame a. Inside this tub is the dasher, in which the clothes are placed, and which consists of the sides b, bottom b', partition b", by means of which the dasher is divided into two chambers, one for large and one for small articles, and swinging covers o c, one for each chamber, having knobs c ck. The sides, bottom, and covers are provided with numerous perforations, so as to allow of the circulation of the water and steam. n

In the center of the dasher is a post, d, from which radiate the perforated paddles c, which are set into the post and extend to the sides b ofthe dasher. These paddles are not vertical,

but are placed at about the angle shown in the drawings, for the purpose below specified.

The dasher rests upon the round plate or carriage f, fixed to the shaft g, passi-n g through the bottom of the tub a and the stuffing-box g', to mechanism which imparts reciprocating rotary motion to it, (the carriage f,) and, by

means of the lugs f', which extend into the 5o bottom b of the dasher from the carriage, to the dasher itself.

The mechanism for imparting reciprocating rotary motion to the shaft g and thence to the dasher is as follows: Power is communicated by a belt to the wheel h, which, with the flywheel h', is fixed upon the shaft 71,",supported in the frames k. The cog-wheel Z, ixed to shaft h, engages the gear-wheel Z', fixed to shaft Zll in framesA The shaft Z turns the crank m, 6o which is secured to it. The connecting-rod n, which extends from crank m to the sleeve o, fixed to the horizontal rod p, imparts reciproeating motion to the rod p, which moves back and forth in the supports p', attached to the 65 frame c. By means of rod r, fixed to the vertical shaft g yand provided with the slot r', in which lies the pin s, extending upward from the sleeve o, fixed to rod p, the reciprocating motion of the rod p produces a reciprocating 7o rotary motion ofthe shaft g, and hence ofthe carriage f and the dasher. Suitable means are provided for preventing the rod p from twisting. The rubber cushionst t, striking alternately the supports p p, are for assisting the crank m to pass its dead-points. The mechanisni having been set in motion and steam applied to the tub ct in any suitable manner, the dasher b b begins to rotate reciproeatingly in the tub and the steam'to enter and circu- 8o late in the dasher by means of the numerous perforations. Thelarger articles-like shirts, for example-are placed one side the partition b", and smaller articles, like collars and cuffs, the other side. As the dasher reciprocates rapidly the articles to be washed do not simply iiy back and forth horizontally, as they would if the paddles were vertical, but they dash from the lower edge of the paddle, forming an acute corner, to the upper portion of the next one, thus traveling a greater distance than-they would if they traveled horizontally. The result is that there is no tying or knotting, as is the case in most washing-machines.

In case there are a number oftubs and dash- Having thus fully described my improvement, what I claim, and desire to secure by Letters Patent, is-

1. The herein-described rotaryreci prooating.,r dasher, the same consisting,` of the perforated bottom b', sides b, und covers c, the partition b, and post cl, said dasher being provided with the inclined puddles e e at substantially the angle shown7 and operated by mechanism substantially as described, for the purpose set forth.

2. The combination of the dasher b b', the carriage j', having lugs f, shaft g, slotted rod o', reciprocziting,` rod p, provided with sleeve o, having piu s l(tud cushions t t, supports p', 1ever and crank n m, and driving-gear operating said crank, substantially as and for the purpose described.
